Ultra-wideband over fiber for broadband wireless access

该项目是欧洲委员会2006年根据信息社会技术第六框架方案批准的“欧洲无线/光子学宽带接入基础设施和实力整合”项目的一部分，目的是为下一代宽带接入应用开发新技术。作为加拿大的唯一合作伙伴，我们将集中精力研究和开发用于宽带无线接入的创新的UWB光纤技术。超宽带于2002年被美国联邦通信委员会批准用于未经许可的用途，近年来一直是一个热门领域，引起了人们对短距离、高通量无线通信和传感器网络的极大兴趣。这样的短距离无线网络可以主要在室内环境中以独立模式运行，几乎不存在与固定有线网络或无线广域基础设施的集成。为了提供跨不同网络的无中断服务，并最终实现随时随地的高速率数据访问，解决方案是将UWB与光纤分配技术相结合，这一新领域称为光纤UWB。在这个项目中，我们将研究在光域中产生和分配UWB信号的光纤UWB体系结构和技术。

This project is part of the European project "InfraStructures for broadband access in wireless/photonics and Integration of Strengths in Europe", approved in 2006 by the European Commission under the 6th Framework Programme of the Information Society Technologies, to develop new technologies for next-generation broadband access applications. As the only partner from Canada, we will concentrate our efforts on the investigation and development of innovative UWB-over-fiber technologies for broadband wireless access. UWB, approved by FCC in 2002 for unlicensed use, has been a hot area recently and has attracted great interests for short-range high-throughput wireless communication and sensor networks. Such short-range wireless networks can operate mainly in indoor environments in a standalone mode, with a nearly nonexistent integration into the fixed wired networks or wireless wide-area infrastructures. To offer availability of undisrupted service across different networks and eventually achieve high-rate data access at any time and from any place, a solution is to combine the UWB with fiber distribution technology, a new area called UWB over fiber. In this project, we will investigate UWB-over-fiber architectures and techniques to generated and distribute UWB signals in the optical domain.
